Hey Folks, I'm looking at potentially getting a 2018 Fit with the 6MT. I'm struggling to find info about how the collision mitigation system works (or doesn't) with the 6MT. It makes perfect sense to me with the CVT, but how does this system (and the adaptive cruise too for that matter) play with the manual transmission given that their operation could potentially lead to stalling the car. Can anyone provide insights? TIA

 

I wasn't aware that the Honda Sensing system was available on MT cars.

 

I don't outright recall the system logic since that's literally the only combo on a GK5 that I haven't driven... BUT it may have be covered on the Accord since CMBS was on the 9th gen and 10th gen manual cars.

 

Totally irrelevant, and not to derail the thread, but man, Hootie, that blue Fit in your sig pic looks SHARP!!! I'm a sucker for fatter than stock tires, that looks like a fun ride

 

Aha, the topic for me, since I explicitly sought out the manual transmission + adaptive cruise combo, pretty much since I learned about the technology.

I am a proud owner of 2019 Fit EX MT6. On Fits, the only way to get MT + Honda-Sensing was 2018 and 2019 EX MT6 in the US market. Honda dropped MT6 on EX for 2020 model year, so the combo disappeared. And as far as I know, a similar combo was never offered in Canada. There might be a similar combo in Japan, but I didn't dig deep.

Surprisingly, the combo is not uncommon, and has been around for years. VW and Porsche had that long ago. Mazda and Toyota also support the combo, but Mazda didn't offer the combo in the US until much later, even though they had the tech from the get go. Subaru, Hyundai/Kia have NEVER supported the combo. Hyundai/Kia does offer automatic emergency braking with MT, but not adaptive cruise control. Their cars haven't been on my list for some time now, as I simply will not buy a car without adaptive cruise control.

Finally to answer the actual question, the emergency braking system will always override pretty much anything else. Engine stall or not, it will do its job by braking.
As for adaptive cruise control, it will only work at 25mph or faster (Fit version). It will just disengage when you fall below that speed with a warning tone. It will NOT disengage when you press down on the clutch for a few seconds, so you can change gear as needed, and it will resume its thing once you let go of the clutch. If you keep the clutch pressed down too long, it will disengage.

It's actually kind of neat to shift gears and continue accelerating without ever touching the accelerator pedal. And you can also downshift.

I don't know if there's a mechanism to disengage if engine RPM drops too low. I doubt it. I'd guess that it really doesn't care about that. 25MPH or faster, and brake pedal is not depressed, nor clutch pedal for too long, then keep trying to do what it needs to do. If clutch is depressed, temporarily disengage. That's of course on top of tracking what in front of the car. Duh.

Having wrote all that, the Honda-Sensing on the Fit is not all that good. It's not smooth at all, and it overreacts in annoying ways. I had a 2015 Subaru Impreza with EyeSight(TM) -- of course CVT -- which was Mom's car, and that thing was impeccable. And that was 4 years older model! It's really too bad Subaru refuses to support MT with EyeSight. If they did, I wouldn't be on this site since I would own a Subaru.

 

Thanks for the info, that's what I was looking for. Unfortunately though, someone else got to the 6speed first. Looks like we're going to get a 2020 CVT.
